Re: [android-developers] Re: TaskAffinity causes new instance being created when startActivity
If you want everything running in the same task, then don't use FLAG_ACTIVITY_NEW_TASK.

[android-developers] Re: TaskAffinity causes new instance being created when startActivity
Thanks, YangJian. What we want is to put all activities started by L stay in the same task as L. So we have to set all activities`s taskAffinity the same one. For that reason, "Single Task" is not for what we want, because it is goint to make A as root of that task which is L in fact. Thanks, Dianne. We just want all activities developed by as in the same task. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Re: TaskAffinity causes new instance being created when startActivity
If they are modelling separate applications, then they each need to have a different task affinity. Having the same affinity means that when you start the activity, it will have an affinity for an existing task with the same name.

RE: [android-developers] Re: TaskAffinity causes new instance being created when startActivity
When L starts A at the step 3 ,you want only one A or two instances of A? If only one , use the flag " singleTask ",if two, do nothing . Can you describe you problem more exactly? I do not understand you want the L A B in the same task or not. -Original Message- From: android-developers@googlegroups.com [mailto:android-develop...@googlegroups.com] On Behalf Of James Wang Sent: Friday, June 11, 2010 12:09 AM To: Android Developers Subject: [android-developers] Re: TaskAffinity causes new instance being created when startActivity Dianne, You are right. We did want to make an activity like launcher. In fact, our product is more complicated than what I said above. Below is the real plan: 1)We made an activity as the launcher L; 2)A tells L to start B; 3)B does something and tells L starts A again. L,A,B have the same taskAffinity. And L starts B and A with NEW_TASK. BTW, I noticed such words in SDK reference: "Similarly, a new instance of a "singleTop" activity may also be created to handle a new intent. However, if the target task already has an existing instance of the activity at the top of its stack, that instance will receive the new intent (in an onNewIntent() call); a new instance is not created. In other circumstances — for example, if an existing instance of the "singleTop" activity is in the target task, but not at the top of the stack, or if it's at the top of a stack, but not in the target task — a new instance would be created and pushed on the stack." It says if A is singleTop, A gets created twice is supposed to be true because A is not on the top of task. But we did not set A as singleTop. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Dianne, You are right. We did want to make an activity like launcher. In fact, our product is more complicated than what I said above. Below is the real plan: 1)We made an activity as the launcher L; 2)A tells L to start B; 3)B does something and tells L starts A again. L,A,B have the same taskAffinity. And L starts B and A with NEW_TASK. BTW, I noticed such words in SDK reference: "Similarly, a new instance of a "singleTop" activity may also be created to handle a new intent. However, if the target task already has an existing instance of the activity at the top of its stack, that instance will receive the new intent (in an onNewIntent() call); a new instance is not created. In other circumstances — for example, if an existing instance of the "singleTop" activity is in the target task, but not at the top of the stack, or if it's at the top of a stack, but not in the target task — a new instance would be created and pushed on the stack." It says if A is singleTop, A gets created twice is supposed to be true because A is not on the top of task. But we did not set A as singleTop. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
